96 VEGETABLE GARDENING. 



Sweet Com Moth or Tassel Worm (Hdiophila unipucta.) This is 

 the boll-worm of the south It eats into the green grain of 

 the corn, but is seldom very troublesome at the north. Dr. 

 Lugger thinks that it does not winter over in the extreme 

 northern states, but that the moths come from the south each 

 year. The only remedy is hand picking. It is doubtful if 

 they will ever become very injurious in the northern states 

 since they do not begin their work there until late in theseason. 



The Parsley Worm or Celery Caterpillar (Pap Mo asterias.) This 

 worm eats the foliage of celery, carrot, parsley and allied 

 plants but is not often very injurious. The mature insect is a 

 beautiful large black butterfly having yellow and blue spots 

 on its wings. The eggs are laid on the foliage and hatch into 

 small caterpillars less than one-tenth of an inch long, which 

 when full grown are one and a half inches long. It has bright 

 yellow markings. The remedy is to hand pick the worms, 

 which are seldom abundant. 



Chinch Bugs (Blissus leucopteris.) The chinch bug does not 

 trouble any of our garden products except corn, but is some- 

 times very injurious to this vegetable and 

 may kill it in a very few days if neglected. 

 This is a sucking insect that winters over 

 in the adult state under leaves and in dry pro- 

 tected places generally. When full grown 

 it is about one-seventh of an inch long with 

 white upper wings, which have two well de- 

 stined black spots on them. When crushed 

 they have an offensive bed-bug-like odor. 

 -.This insect is not affected by cold weather 

 but succumbs quickly to moisture. The fe- 

 male deposits her eggs near theground upon

Remedies. The burning of rubbish accumulations along 

 headlands, fences, etc., in the winter or early spring in in- 

 fested localities will destroy many. They always infest the 

 small grains before they do corn. 



While these insects have wings they use them but little in 

 their migrations in summer. They travel on foot and often 

 in great numbers. Taking advantage of these peculiarities, 

 they may be kept from corn fields by plowing deep furrows in
